UE2 - UT2kX Help, my character mesh and textures look messed up once imported into UT2004 :(

Hey guys, my character mesh and its texture all look messed up once it is imported into UT2004, i don't know what the problem is, i mean, my character looks fine in Maya, like the mesh and the texture is showing up correctly and all, but once i imported it into UT2004, my character look messed up, everything gone wrong , the texture all look screwed up except for the character's jacket, that is the only part where the texture isn't messed up, why is that??? Do u guy know what the problem is??? god forbid is it a bug in UT2004? or maya2008?? that is causing this problem????

Here is a screen shot i took to show u guys of what i'm talking about( http://img241.imageshack.us/my.php?image=helpan5.jpg )

I couldn't figured out what my problem is, i only have 1 mesh and 1 texture file that is properly painted and layout. My character mesh is properly rigged as it animates just fine in Maya, i have double checked that my skeleton has no underscore or spaces.
I'm very disappointed, i spent so much time on the character and it look messed up in UT , please tell me what my problem is!!!

Thanks Leilei, my character mesh and its texture is displaying perfectly fine now. Now i have another problem, in maya my character's walk cycle and his attacking animation works perfectly fine, but after importing it into UT2004 and played animations, my character's head got stretched and disjointed from the body when he is doing his attacking animation, and for his walk cycle, his leg look like it's disjointed from the body too, Do u know what is causing this problem??? thanks in advance!! you're a great helper!!

Can anyone help????

Never mind, i have resolved my problem! i had 2 extra pieces of separate bones locked onto the character's skeleton to control the leg's movement, so yeah, those bones screwed up my mesh cause it isn't connected with the rest of the skeleton, so yeah, i reconnect them and that fixed my problem!!
